A, B, and C invested Rs. 6300, Rs. 4200, and Rs. 10500 respectively in a joint business venture. If the total profit after one year is Rs. 12,100, what is A's portion of the profit?

Explanation

The investment ratio of A, B, and C is 6300:4200:10500, which simplifies to 3:2:5. The total parts are 3 + 2 + 5 = 10. Therefore, A's share is (3/10) of Rs. 12,100, which equals Rs. 3630.
